Best alternatives to Open-Generative-AI in 2026

Most AI image and video generators — Midjourney, Runway, Sora — are subscription services running on someone else's servers, with their own rules about what you can and can't generate. Open-Generative-AI flips that: it's a free program you install and run yourself, bundling access to over 500 different image and video generation models in one interface, with no monthly fee and no company reviewing your prompts. Open-Generative-AI is a self-hosted, MIT-licensed studio unifying 70+ text-to-image models, 70+ image-to-image models, 85+ text-to-video models, and 120+ image-to-video models (spanning Flux, Midjourney-style, Kling, Sora-style, and Veo-style architectures) behind one interface, plus a dedicated 15-model Lip Sync Studio and a drag-and-drop Workflow Builder for chaining generation steps into pipelines. It supports multi-image reference input (up to 14 images), local inference via a bundled stable-diffusion.cpp runtime plus optional remote inference (Wan2GP), browser-based generation history, and ships as desktop apps for macOS/Windows/Linux, a Node.js web version, or Docker Compose for server deployment. It hit GitHub Trending in April 2026 and has grown to over 27,000 stars and 4,700+ forks with frequent commits, making it one of the more actively maintained self-hosted generation studios.
